70D Multiple exposures

Things were going along pretty well with 7 exposures producing 7 images of same scene all going off right after another with a continuous drive setting. Now, somehow there are 7 images per each of the 7 exposures. 7x7 get's me 49 images. I finally figured out what it was doing by scrolling through the 48 images. Every 7th click of the wheel would then bring up the next exposure level, etc.
